Constraint-Free Coherent Diffraction Imaging via Physics-Guided Neural Fields
Zhe Hu, Zisheng Yao, Yuhe Zhang +1
CDI is a lensless imaging technique that enables atomic-resolution imaging of non-crystalline specimens and their dynamics. However, its broader implementation has been hindered by…
Optimizing probes for multi-beam ptychography
Runqing Yang, Pablo Villanueva-Perez, Maik Kahnt
Multi-beam ptychography (MBP) offers a scalable solution to improve the throughput of state-of-the-art ptychography by increasing the number of coherent beams that illuminate the s…
Time-resolved 3D imaging opportunities with XMPI at ForMAX
Julia Katharina Rogalinski, Zisheng Yao, Yuhe Zhang +11
X-rays are commonly used in imaging experiments due to their penetration power, which enables non-destructive resolution of internal structures in samples that are opaque to visibl…
Super time-resolved tomography
Zhe Hu, Kalle Josefsson, Zisheng Yao +4
Understanding 3D fundamental processes is crucial for academic and industrial applications. Nowadays, X-ray time-resolved tomography, or tomoscopy, is a leading technique for in-si…
Physics-informed 4D X-ray image reconstruction from ultra-sparse spatiotemporal data
Zisheng Yao, Yuhe Zhang, Zhe Hu +3
The unprecedented X-ray flux density provided by modern X-ray sources offers new spatiotemporal possibilities for X-ray imaging of fast dynamic processes. Approaches to exploit suc…
